Network Planning
The private local network, connected to the LAN port or wireless interface, provides
a Dynamic Host Configuration Protocol (DHCP) server for allocating IP addresses to
local PCs and wireless clients, and Network Address Translation (NAT) for mapping
the multiple "internal" IP addresses to one "external" IP address.
The public external network, connected to the WAN port, supports DHCP client,
Point-to-Point Protocol over Ethernet (PPPoE) and static IP for connection to an
Internet service provider (ISP) through a cable or DSL modem.
The 3G Modem link can provide a backup Internet connection with automatic
failover and fallback to the primary WAN connection.

LAN Access Point

The wireless AP/Router can provide an access point service for an existing wired
LAN, creating a wireless extension to the local network. The wireless AP/Router
functions as purely an access point when set to AP Mode. When used in this mode,
there are no gateway functions between the WAN port and the LAN and wireless
interface.
A Wi-Fi wireless network is defined by its Service Set Identifier (SSID) or network
name. Wireless clients that want to connect to a network must set their SSID to the
same SSID of the network service. The wireless AP/Router supports two separate
wireless interfaces, that is two SSIDs or Virtual Access Points (VAPs). The two VAP
interfaces can be configured separately to support different security settings or other
wireless functions.
